Marine Damage Surveys & Boat Damage Inspections in San Diego

Great River & Lakes – Marine Surveying Co. provides professional marine damage surveys and boat damage inspections in San Diego, California for vessel owners, insurance companies, attorneys, lenders, marinas, repair facilities, and other parties requiring independent documentation of vessel damage.

Our Southern California marine surveyors inspect damaged recreational boats, yachts, sailboats, powerboats, and commercial vessels throughout San Diego Bay and surrounding San Diego County marine facilities.

Damage surveys are available for incidents involving collisions, groundings, storms, fires, flooding, machinery failures, dock damage, transportation incidents, and other marine casualties.

What Is a Marine Damage Survey?

A marine damage survey is an independent inspection performed to document the observable nature and extent of damage to a boat or yacht.

Depending on the assignment, the surveyor may document:

  • Areas of visible damage

  • Structural damage

  • Hull damage

  • Machinery damage

  • Electrical damage

  • Water intrusion

  • Damaged equipment

  • Affected vessel systems

  • Observable pre-existing conditions

  • Recommended additional investigation

  • Repair considerations

  • Photographs and supporting documentation

The exact scope depends on the casualty, vessel type, accessibility, and requirements of the client or insurance company.

Insurance Claim Boat Inspections in San Diego

Great River Marine Surveying provides insurance damage claim surveys for boats and yachts throughout San Diego.

A marine insurer may request an independent survey after a loss to help document the condition of the vessel and the extent of observable damage.

We can assist with claims involving:

  • Collision damage

  • Groundings

  • Docking accidents

  • Storm damage

  • Fire damage

  • Flooding

  • Water intrusion

  • Machinery failures

  • Propeller and running-gear damage

  • Transportation damage

  • Marina incidents

  • Impact damage

Our surveyor documents observations independently based on conditions accessible at the time of inspection.

Collision Damage Surveys

Boat collisions can affect far more than the immediately visible exterior surface.

Depending on the location and severity of an impact, damage may involve:

  • Hull laminate

  • Frames and structural members

  • Bulkheads

  • Deck-to-hull connections

  • Rub rails

  • Swim platforms

  • Running gear

  • Propellers

  • Shafts

  • Rudders

  • Steering systems

  • Interior components

A marine damage inspection can help document both visible impact areas and accessible surrounding structures that may warrant additional evaluation.

Grounding Damage Inspections

A grounding can damage underwater components even when relatively little damage is visible above the waterline.

When a vessel has grounded, inspection may include accessible portions of the:

  • Hull bottom

  • Keel

  • Propellers

  • Shafts

  • Struts

  • Rudders

  • Saildrives

  • Outdrives

  • Trim tabs

  • Through-hull fittings

  • Transducers

  • Structural attachment areas

Haul-Out After a Grounding

A haul-out is often appropriate following a grounding because underwater components cannot be adequately evaluated while the vessel remains afloat.

Where practical, our surveyor can coordinate the damage inspection with the vessel's marina or boatyard so the underwater hull and running gear can be examined.

Storm & Weather Damage Surveys

Southern California vessels can experience damage from wind, waves, heavy weather, dock impacts, line failures, debris, and other environmental events.

A storm-related marine damage survey may document:

  • Hull damage

  • Deck damage

  • Broken hardware

  • Damaged railings

  • Window or hatch damage

  • Water intrusion

  • Rigging damage

  • Docking damage

  • Electrical problems

  • Machinery exposure

  • Interior water damage

The survey report documents observable conditions present during the inspection.

Fire Damage Surveys

Marine fires can affect structural materials, wiring, machinery, plumbing, fuel systems, interior components, and surrounding equipment.

Depending on accessibility and the requested scope, a fire damage survey may document:

  • Areas of direct fire damage

  • Heat-affected components

  • Smoke damage

  • Electrical system damage

  • Machinery damage

  • Structural concerns

  • Interior damage

  • Fire suppression equipment

  • Areas requiring further specialized evaluation

Fire-damaged vessels may require additional inspection by electrical, mechanical, structural, or fire-investigation specialists depending on the circumstances.

Water Intrusion & Sinking Damage

We provide damage surveys for boats and yachts affected by flooding, partial sinking, complete submersion, leaking systems, or other forms of water intrusion.

Potentially affected areas may include:

  • Engines

  • Generators

  • Electrical systems

  • Batteries

  • Electronics

  • Fuel systems

  • Interior finishes

  • Machinery

  • Pumps

  • Wiring

  • Structural components

Prompt documentation can be particularly important after significant water exposure because vessel conditions can continue to change after the initial casualty.

Machinery Damage Surveys

Marine damage is not limited to the hull.

Depending on the assignment, our surveyors can document observable damage involving:

  • Engines

  • Transmissions

  • Generators

  • Propulsion systems

  • Steering equipment

  • Cooling systems

  • Exhaust systems

  • Electrical equipment

  • Pumps

  • Auxiliary machinery

Specialized engine technicians or other technical specialists may be recommended when manufacturer-specific diagnostics or internal mechanical evaluation is required.

Propeller, Shaft & Running-Gear Damage

Propellers, shafts, struts, rudders, outdrives, and other underwater components can be damaged by groundings, submerged objects, debris, fishing line, dock incidents, or other impacts.

A haul-out inspection may allow the surveyor to document:

  • Propeller damage

  • Shaft damage

  • Strut damage

  • Rudder damage

  • Outdrive damage

  • Trim-tab damage

  • Visible alignment concerns

  • Hull damage surrounding running gear

  • Damaged through-hull components

Additional mechanical or alignment testing may be recommended based on observed conditions.

Dock & Marina Damage Inspections

Damage can occur while a vessel is secured at a marina as a result of:

  • Dock impacts

  • Neighboring vessels

  • Failed dock hardware

  • Line failures

  • Wake damage

  • Wind events

  • Electrical incidents

  • Marina equipment

  • Falling objects

  • Other dockside events

Our surveyors can inspect vessels at accessible San Diego marinas, docks, boatyards, and repair facilities.

Transportation Damage Surveys

Boats and yachts can also be damaged during overland transportation, loading, unloading, launching, lifting, or storage.

Transportation-related inspections may involve:

  • Hull impact damage

  • Scratches and abrasions

  • Structural concerns

  • Damaged rails or hardware

  • Propeller or running-gear damage

  • Trailer-related damage

  • Lifting-point damage

  • Interior movement or equipment damage

Photographic documentation and timely inspection may be valuable when multiple parties are involved.

Sailboat & Rigging Damage Surveys

We also provide marine damage inspections for sailboats.

Depending on the casualty and accessibility, damage inspection may include observable portions of:

  • Mast

  • Boom

  • Standing rigging

  • Running rigging

  • Chainplates

  • Deck hardware

  • Steering systems

  • Keel

  • Rudder

  • Structural attachment areas

A specialized rigger may also be recommended when detailed rigging evaluation is required.

  • Sportfishing boats

  • Express cruisers

Larger vessels may require coordination with boatyards, mechanics, electricians, fiberglass specialists, or other marine professionals depending on the damage involved.

What Does a Marine Damage Survey Report Include?

Depending on the requested scope, a professional damage survey report may include:

  • Vessel identification

  • Date and location of inspection

  • Description of reported incident

  • Areas inspected

  • Observable damage

  • Photographs

  • Relevant vessel conditions

  • Recommendations for additional investigation

  • Repair-related observations

  • Supporting documentation

The report is based on conditions observable and accessible during the inspection.

Does a Damage Survey Determine Insurance Coverage?

A marine surveyor documents the vessel and observed damage.

Decisions regarding insurance coverage, policy interpretation, liability, payment, or legal responsibility are made by the insurer and other appropriate parties rather than by the vessel survey itself.

The survey provides independent technical documentation that may assist those parties in evaluating the claim.

Damage Survey Before Repairs Begin

When practical, having the damaged vessel inspected before substantial repairs begin can help preserve documentation of the original condition.

If emergency repairs are necessary to prevent further damage, owners should retain photographs, invoices, damaged components when practical, and other relevant documentation.

The circumstances of each casualty are different, so inspection timing should be coordinated with the insurance company and repair facility when applicable.
